Adjustable Power supply / Power regulator board.
EID78ADJ board is designed to convert 26-30 Volts AC (half wave) or DC
input voltage to stabilize custom adjustable DC voltage output (1.25 to 24V DC). If used properly, it will eliminate the need for
expensive industrial power supplies, which would otherwise be needed to carry out the same
is easy to install, setup and
operate. If you want to professionally power your HVAC products,
EID78ADJ offers the features you need. Mounted easily via one 0.125" mounting
holes. or directly solder to your board through 3 pins.
board is designed to attenuate, filter and regulate 26-30V DC or AC to
stable custom V DC.
